2015-03-07Input: psmouse - disable "palm detection" in the focaltech driverMathias Gottschlag1-10/+0
Apparently, the threshold for large contact area seems to be rather low on some devices, causing the touchpad to frequently freeze during normal usage. Because we do now know how we are supposed to use the value in question, this commit just drops the related code completely.

2015-03-07Input: psmouse - disable changing resolution/rate/scale for FocalTechMathias Gottschlag3-1/+44
These PS/2 commands make some touchpads stop responding, so this commit adds some dummy functions to replace the generic implementation. Because scale changes were not encapsulated in a method of struct psmouse yet, this commit adds a method set_scale to psmouse.

2015-03-07Input: psmouse - ensure that focaltech reports consistent coordinatesMathias Gottschlag1-2/+10
We don't know whether x_max or y_max really hold the maximum possible coordinates, and we don't know for sure whether we correctly interpret the coordinates sent by the touchpad, so we clamp the reported values to prevent confusion in userspace code.

2015-03-04Input: tc3589x-keypad - set IRQF_ONESHOT flag to ensure IRQ requestValentin Rothberg1-3/+3
Since commit 1c6c69525b40eb76de8adf039409722015927dc3 ("genirq: Reject bogus threaded irq requests") threaded IRQs without a primary handler need to be requested with IRQF_ONESHOT, otherwise the request will fail. Currently, plat->irqtype is only set to IRQF_TRIGGER_FALLING. This patch sets the ONESHOT flag directly in request_threaded_irq() to enforce the flag without being affected by future changes to plat->irqtype.

2015-03-02Input: sun4i-ts - add thermal driver dependencyArnd Bergmann1-0/+1
The sun4i-ts driver has had a dependency on the thermal code with the addition of the thermal zone sensor support, but this is not currently enforced in Kconfig, so with TOUCHSCREEN_SUN4I=y, THERMAL=m and THERMAL_OF=y we get drivers/built-in.o: In function `sun4i_ts_remove': :(.text+0x2376f4): undefined reference to `thermal_zone_of_sensor_unregister' drivers/built-in.o: In function `sun4i_ts_probe': :(.text+0x237a94): undefined reference to `thermal_zone_of_sensor_register' :(.text+0x237c00): undefined reference to `thermal_zone_of_sensor_unregister' We need the dependency on THERMAL in order to ensure that this driver becomes a loadable module if the thermal support itself is modular, while the dependency on THERMAL_OF is a runtime dependency and the driver will still build if it is missing. It is entirely possible to build sun4i-ts without THERMAL_OF just to use the hwmon sensors and/or touchscreen.

2015-02-15Input: ALPS - do not mix trackstick and external PS/2 mouse dataPali Rohár2-53/+151
Previously dev2 device was used for both external PS/2 mouse and internal trackstick device (if available). This change introduces dev3 device which is used for external PS/2 mouse data and dev2 is now used only for trackstick. In case that trackstick is not present dev2 is not created, so userspace does not see non existent device in system. Because laptops with ALPS devices often do not use i8042 active multiplexing all data (from touchpad, trackstick and external PS/2 mouse) come to one port. So it is not possible to know if external PS/2 mouse is connected or not. In most cases external PS/2 mouse is not connected so driver will create dev3 input device after first bare PS/2 packet will be received. So there will not be "ghost" input device. This change also helps in identifying possible problems in future if driver decides to report 6-bytes trackstick packets as 3-bytes bare PS/2 (data will be reported to dev3 instead dev2).

2015-02-15Input: ALPS - fix trackstick detection on some Dell LatitudesDmitry Torokhov1-22/+56
On some Dell Latitudes we fail to identify presence of trackstick unless we reset the device. The issue is quite benign as we do perform reset in alps_init(), so the trackstick ends up working, but mouse name reported to userspace is not accurate. In order to fix the issue while avoiding the additional lengthy reset we move the resrt to alps_detect() and keep the discovered state to be used later in alps_init().

KEY_HOME is the key to go back to the beginning of the line, not the key to get into an overview mode, as Windows does. GNOME can already make use of the Windows key on multiple form factors, and other desktop environments can use it depending on the form factor. Using "Windows" as the emitted key also means that the keycode sent out matches the symbol on the key itself. So switch KEY_HOME to KEY_LEFTMETA ("Windows" key).

2015-02-03Input: synaptics - use dmax in input_mt_assign_slotsBenjamin Tissoires1-1/+4
When tapping a clickpad with two fingers, there is a chance that the sensor sees first only one finger, and at the next scan only the second one. In this case, the sensors says that there has been only one finger on the clickpad, which moved really fast between two scans. We can try to counter this by adding a limit to what an actual finger can move between 2 scans. A distance of 1cm between two scans for one finger seems reasonable. However, this is not really accurate because the resolution in X and in Y differs. But heh, that's how the in-kernel tracking works right now, and its job is quite good, even with this approximation. This parameter solves most of the jumps observed, not all of them however. But this is a hardware defect, and we might not be able to get something better without much heavier computations.

Previously, delta filtering was applied TSC co-ordinate readouts before reporting a single value to user space. This patch replaces delta filtering with median filtering. Median filtering sorts co-ordinate readouts, drops min and max values, and reports the average of remaining values. This method is more sensible than delta filtering. Median filtering is applied only if number of readouts is greater than 3 else just average of co-ordinate readouts is reported.

2015-02-03Input: ti_am335x_tsc - remove udelay in interrupt handlerBrad Griffis1-36/+31
TSC interrupt handler had udelay to avoid reporting of false pen-up interrupt to user space. This patch implements workaround suggesting in Advisory 1.0.31 of silicon errata for am335x, thus eliminating udelay and touchscreen lag. This also improves performance of touchscreen and eliminates sudden jump of cursor at touch release. IDLECONFIG and CHARGECONFIG registers are to be configured with same values in order to eliminate false pen-up events. This workaround may result in false pen-down to be detected, hence considerable charge step delay needs to be added. The charge delay is set to 0xB000 (in terms of ADC clock cycles) by default. TSC steps are disabled at the end of every sampling cycle and EOS bit is set. Once the EOS bit is set, the TSC steps need to be re-enabled to begin next sampling cycle.

2015-02-03Input: ti_am335x_tsc - interchange touchscreen and ADC stepsBrad Griffis1-18/+24
This patch makes the initial changes required to workaround TSC-false pen-up interrupts. It is required to implement these changes in order to remove udelay in the TSC interrupt handler and false pen-up events. The charge step is to be executed immediately after sampling X+. Hence TSC is made to use higher numbered steps (steps 5 to 16 for 5 co-ordinate readouts, 4 wire TSC configuration) and ADC to use lower ones. Further X co-ordinate readouts must be the last to be sampled, thus co-ordinates are sampled in the order Y-Z-X.

2015-02-01Input: MT - add support for balanced slot assignmentHenrik Rydberg6-16/+25
Some devices are not fast enough to differentiate between a fast-moving contact and a new contact. This problem cannot be fully resolved because information is truly missing, but it is possible to safe-guard against obvious mistakes by restricting movement with a maximum displacement. The new problem formulation for dmax > 0 cannot benefit from the speedup for positive definite matrices, but since the convergence is faster, the result is about the same. For a handful of contacts, the latency difference is truly negligible.

The Allwinner A31 SoC (sun6i) has the same resistive touchpanel controller as on other sunxi platforms. The only difference between the variants is the control bits for enabling operations are left-shifted by 1 on the A31. Also update the comment for the original temperature sensor with information from Allwinner. Signed-off-by: Chen-Yu Tsai <wens@csie.org> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
